Types of RV Water Heaters – Choosing the Best Hot Water Solution for Your RV

When you’re living or traveling in an RV, few amenities feel as essential as hot water. After a day of hiking dusty trails or setting up camp in chilly weather, a hot shower is more than a luxury — it’s a necessity. The right RV water heater makes that possible. But with so many models and technologies available, it’s worth taking the time to understand the types of RV water heaters and how each one fits different travel styles and needs.

This guide explores the main categories — tank, tankless RV water heaters, and hybrid systems — along with the fuel sources that power them, the features to look for, and tips to help you select the perfect solution for your RV.

Choosing an RV water heater is about more than just getting hot water. It affects your daily comfort, how much energy you consume, and even how much space you have available for storage. Your choice will depend on factors like how often you travel, the climates you visit, and whether you typically camp with full hookups or prefer off-grid adventures.

Water heaters come in different configurations that run on propane, electricity, or a combination of both. Propane-powered RV water heaters are reliable when you’re camping without access to shore power, while electric RV water heaters excel in campgrounds where hookups are available. Dual-fuel RV water heaters offer the flexibility to switch between the two depending on your situation.

Tank-style RV water heaters are the most traditional option, and they work much like the water heater in a stationary home — storing a fixed amount of heated water in a tank, usually between six and ten gallons. When you open a hot water tap, heated water is pulled from the tank, and the system automatically reheats the incoming cold water.

The appeal of tank-style systems lies in their simplicity and affordability. They are widely available, relatively easy to install, and straightforward to maintain. For weekend campers or travelers who use hot water in smaller bursts, these heaters can be a dependable choice.

However, they do have limitations. Once the stored hot water is used up, you’ll need to wait for the heater to recover and bring the new water up to temperature. If you’re camping with several people, this could mean spacing out showers to avoid running out of hot water. If you’re replacing an older model, you can explore RV water heater replacement options compatible with your current rig.

Tankless, or on-demand, water heaters heat water instantly as it flows through the system, providing a virtually endless supply. This makes them ideal for families or full-time RVers who want the convenience of hot water whenever it’s needed, without worrying about running out mid-shower.

In addition to offering continuous hot water, tankless models are more compact, freeing up valuable storage space. They can also be more energy-efficient, since they only heat water when you’re actively using it. Lippert’s Furrion® tankless RV water heaters and Girard tankless RV water heaters add extra convenience with features like freeze protection, precise temperature control, and compatibility with standard RV water heater openings for easy retrofits.

While tankless systems tend to have a higher upfront price than tank models, the long-term benefits — like never running out of hot water — often outweigh the initial cost for many RVers.

Propane remains the most common fuel source for RV water heaters, largely because of its reliability and portability. It allows you to heat water whether you’re plugged into shore power or boondocking miles away from the nearest hookup. Electric-powered models work best in campgrounds with electrical service, offering quiet, efficient operation.

For those who want flexibility, dual-fuel RV water heaters allow you to switch between propane and electricity as needed, making them a great choice for RVers who explore a variety of environments.

When comparing models, consider factors like BTU rating for heating performance, voltage requirements (many operate on 12V, but some electric elements need 120V), and door size compatibility for replacements. Lippert offers a wide range of RV water heater parts and RV water heater doors to ensure the right fit for your setup.

Safety features — such as freeze protection, temperature control, and pressure relief valves — help ensure reliable operation in all conditions.

The best choice depends on your travel habits and environment. Weekend campers in warm climates may find a basic tank-style unit perfectly adequate. Full-time travelers or those visiting colder areas may benefit from tankless or hybrid models with advanced temperature regulation.

If space is at a premium, compact tankless units can free up storage. For those who camp without hookups, propane or dual-fuel RV water heaters provide dependable performance without relying on electrical connections.

Proper installation ensures safety and efficiency, which is why many RV owners choose professional installation for their water heaters. Once installed, ongoing care is essential, and it's important to follow the recommendations of the manufacturer of you runit. Seasonal preparation — like winterizing your RV water heater — is crucial for preventing freeze damage.
